介绍了一种低温搪瓷釉的助熔剂,有效将搪瓷的烧成温度降至800℃以下,研究了烧成温度和保温时间对搪瓷层耐酸性能、抗机械冲击性能以及耐温急变性能的影响。结果表明:所制备搪瓷层的耐酸性能、抗冲击性能以及耐温急变性能都达到了国家优等品的标准,随着烧结温度的提高和保温时间的延长,搪瓷层的耐酸性能和抗机械冲击性能均提高。最后,运用有限元分析软件ANSYS分析了搪瓷层的传热性能,以及热应力对搪瓷层稳定性的影响。

A flux of low-temperature enamel glaze was introduced, with which the sintering temperature of the enamel was put down to 800℃. The effects of sintering temperature and holding time on the acid corrosion resistance, impact resistance and thermal shock resistance of enamel coating were investigated. The experiment results showed that the acid corrosion resistance, impact resistance and thermal shock resistance had all reached to the national superior product standard, and the acid corrosion resistance and impact resistance were improved with the increase of sintering temperature and holding time. At the end, the effect of thermal conduction and thermal stress on enamel coating stability was investigated with the commercial software ANSYS.
